我如何在Java中吐温？ [英] How do I tween in Java?

问题描述

我寻找到做在Java中的2D游戏，我碰到的动画一个问题：我该怎么办的渐变？是否有任何库，或者也可以是我能找到的绑定？

I'm looking into making a 2D game in Java and I've run into a problem with animation: how do I do tweening in Java? Are there any libraries or maybe something I can find bindings for?

另外，请大家明白，我不想简单地移动图像，我想这样做的方式，对动画制作的图纸时，我可以用几个关键帧，以填补在中间帧生成动画变形

Also, please understand that I do not want to simply move an image, I want to do morphing in a way that when making drawings for animation I can use a few keyframes to fill in the in-between frames to generate the animation.

推荐答案

我建立了一个通用吐温引擎的Java：
HTTP：//$c$c.google.com/p/ Java的通用吐温引擎/

I built an Universal Tween Engine for Java: http://code.google.com/p/java-universal-tween-engine/

吐温可以应用到每一个对象（不只是图形对象，应有尽有！），每个对象属性可补间，它支持所有的罗伯特·彭纳缓和方程了。

Tweens can be applied to every object (no just graphics objects, everything!), every object attribute can be tweened, and it supports every Robert Penner easing equation too.

而且，发动机被优化以不实例在运行任何东西（除了初始化期间），所以它可用于Android游戏而不用担心垃圾收集

Also, the engine is optimized to not instantiate anything at runtime (except during initialization), so it can be used for Android games without fearing the garbage collector.
